Drivers of large carnivore density in non‐hunted, multi‐use landscapes

Conservation Science and Practice, Volume 5, Issue 1, January 2023., 2023
Abstract Protected areas serve as population strongholds for many large carnivores, with multi‐use landscapes along their borders forming the front‐lines of wildlife conservation. Understanding large carnivore population dynamics within working landscapes is difficult where anthropogenic mortality is high and unregulated.

Identification and Determination of the Seminiferous Epithelium Stages and Spermatid Development in the Testis of Aceh Bull (Bos indicus)

Veterinary Medicine International, Volume 2023, Issue 1, 2023., 2023
This study was conducted to describe the stages of seminiferous epithelium (SE), determine the relative frequency of the stages, and identify the steps of spermatid development during spermatogenesis in the testicular tissue of Aceh bull. Seven pairs of the testicular organs of Aceh bull (Bos indicus) were used and then processed in a histological ...

Roadkill patterns in Latin American birds and mammals

Global Ecology and Biogeography, Volume 31, Issue 9, Page 1756-1783, September 2022., 2022
Abstract Aim Roads are a major threat for wildlife, degrading habitat and causing mortality via wildlife–vehicle collisions. In Latin America, the conjunction of high biodiversity and a rapidly expanding road network is reason for concern. We introduce an approach that combines species traits and habitat preferences to describe vulnerability and map ...

Limited temporal response of Cerrado mammals to anthropogenic pressure in areas under distinct levels of protection

Journal of Zoology, Volume 317, Issue 1, Page 43-55, May 2022., 2022
We used camera trap data to investigate whether Cerrado mammals would shift part of their activity towards the night in response to anthropogenic pressure. Our results revealed that 12 out of 14 species investigated did not show a temporal response to pressure.

Large wild herbivores slow down the rapid decline of plant diversity in a tropical forest biodiversity hotspot

Journal of Applied Ecology, Volume 58, Issue 11, Page 2361-2370, November 2021., 2021
Our study indicates that large herbivores have moderate yet critical effects on slowing down community change and diversity loss of highly diverse plant communities, thus suggesting that the conservation of (and potentially trophic rewilding with) large herbivores is a fundamental nature‐based solution for averting the global collapse of the ...

Contrasting origin of B chromosomes in two cervids (Siberian roe deer and grey brocket deer) unravelled by chromosome-specific DNA sequencing. [PDF]

, 2016
BACKGROUND: B chromosomes are dispensable and variable karyotypic elements found in some species of animals, plants and fungi. They often originate from duplications and translocations of host genomic regions or result from hybridization. In most species,

Evaluation of potential reproductive seasonality in brown brocket deer (Mazama gouazoubira) bucks

Theriogenology, 2021
Photoperiod is the main cue that controls seasonal reproduction in deer from temperate regions, like secretion of testosterone by the testis, neck enlargement, and testis development. However, little is known about its effect on the reproduction of tropical deer species. This research aimed to assess the potential seasonality of the brown brocket deer (
